Husband has antagonism towards dependant (6-2)
I believe the answer is:
hanger-on
'dependant' is the definition.
(someone who hangs on others)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hanger-on that I've seen before include "Sycophantic associate" , "Persistent follower" , "Dependent - sycophantic follower" , "Unwanted follower or dependant, parasite" , "A sycophant - he really clings" .)
